I decided after getting these sheets that I will only ever buy temperature regulating sheets for myself from now on! :D I have Ehlers Danlos Syndrome and Dysautonomia (a dysfunctional autonomic nervous system) so I do not regulate my temperature well at all. It can make me very sick. These help a lot though since my problem is extreme it is not a 100% fix. But they have made a big difference. I definitely recommend them for everyone, even if your internal temperature control works.
